DeFacto

An open source, crowd sourcing information initiative to stop the dissemination of so called "fake news" and "alternative facts." Visit the website

DeFacto is more than just a database, it's an open, RESTful web API that utilizes machine learning techniques and fantastic APIs such as Microsoft Cognitive Services to help everyday users to determine whether or not news sources are credible.
DeFacto also collects helpful data about news sources that can be used for data analysis, tracking, and machine learning training models via user generated fact-checking and article ranking.

Actively collects information on credible and non-credible sources/articles
Machine learning and Natural Language Processing (NLP) combine to inform users about the content their reading intuitively.
Changes credibility values based on user input Because you shouldn't find out your 'credible' news sources aren't credible after the fact. DeFacto -- Get The Facts, Yo.
